A few weeks ago I post an article about a puzzle on a beer coaster called Bolleke Puzzle. Luckily I found two other “Bolleke” puzzle coasters.

The rules are simple: Each row and column has to have the same number of solid and open circles. Next to that you are not allowed to have more than the same type of “Bollekes” next to each other (solid and open). And as proven on Puzzlinks when there is a unique solution in each square there has to be a “Bolleke”. Happy Puzzling!
